FEvLLlNG-GUIDE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 458,428, dated August25, 1891.

Application filed March 10, 1890. Renewed Iehuary 3, 1891. Serial No.379,973. (No model.)

To all whom it may concern:

Be it known that we, CHARLES H. PEIESTER and CONRAD SCHTZ, both citizensof the United States, and residents of Philadelphia,

Pennsylvania, have invented certain Improvements in Feller-Guides forSewing-Machines, of which the following is a specification.

One object of our invention is to so construct a felling-guide forsewing-machines ro that the edges of the fabric which are to be felledand united may be fed into the guide perfectly straight-that is to say,without any preliminary folding, partial folding, or othermanipulation-the folding and interlocking of the edges of the fabricbeing effected wholly by reason of the peculiar conformation of theguide.

A further object of the invention is to simplify and cheapen theconstruction of the deeo vice.

These objects we attain in the manner herein set forth, reference beinghad to the accompanying drawings, in which- Figure 1 is a plan view of afelling-guide for sewing-machines constructed in accordance with ourinvention. Figs. 2, 3, et, 5, 6, 7, 8, 9, and 10 are transversesectional views of the saine on the correspondingly-numbered lines ofFig. 1. Fig. 1l is a plan view of another form of felling-guideconstructed in accordance with our invention and Figs. 12, 13, 14, 15,16, 17, and 18 are transverse sections of the same on thecorrespondingly-nullibered lines of Fig. 11.

The guide shown in Fig. 1 consists of a single plate A of sheet metalcontracted in width at the front end, so as to form a projecting fingera, the widenedv rear portion forining lateraliy-projecting guide-fingerso b, one 4o of which is preferably extended, as at b2, and

is slotted, as at b3, for the reception of a setscrew, whereby it issecured to the work-plate of the machine. The central portion of theplate is bent into S shape, as shown in Fig. 2, so as to provide twoguides, one above the other, these guides being horizontal at thereceiving end of the device, and the upper guide serving as a bearingfor the edge of the upper layer of fabric, while the lower guide consti-5o tutes a bearing for the edge of the lower layer,

the S shape of the central portion of the guide permitting these edgesto overlap to the desired extent and the horizontal character of theguides permitting the fabric to enter the same without any bending ormanipulation. 55 The S form of the central portion of the guide iscontinued throughout the entire length of the finger a; but said fingeris twisted-to the extent of a half-turn in its length, so that as thefabric is fed forward through the finger the edge of the upper layer offabric will be turned downward and inward and the edge of the lowerlayer will be turned upward and inward. Hence the two edges will becaused to interlock before they issue from the guide and pass to theneedle or needles whereby the seain is formed.

In Fig. 1 we have shown at mfr the relation 0f the needles of themachine to the delivery end of the finger a when the attachment is usedin connection with a double-needle machine. Vhen the attachment is usedon a single-needle machine, the needle will occupy a position aboutmidway of the points 00.

In some cases where it is desired to brace the wings l) and to moreclosely confine the two layers of fabric where they enter the guide,said wings b of the plate may be combined with separate plates b b',soldered or otherwise secured in position, as shown in Figs. 11, 12, and13, the construction of the guide there shown being in other respectssubstantially similar to that of Fig. 1.

Having thus described our invention, we claim and desire to secure byLetters Patent 8 5 1. The within-described felling-guide forsewing-machines, the same consisting of a plate having an S-shaped guideforming at the receiving end straight grooves one above the other, buthaving a projecting finger twisted to the extent of a half-turn, wherebythe folding and interlocking of the edges of the fabric is effected,substantially as specified.

2. Afelling-guide for sewing-machines, consisting of a plate having acentral projecting linger contracted in width and laterally-proj ectingwings-at the rear of the same, the central portion of the plate beingbent into S shape and forming at the entrance end grooves or passagesone above the other, the projectroo ing finger being twisted totheextent of a haifnames to this specification in the presence of turn inits length, substantially as speeied. two subscribing' Witnesses.

3. The combination of the S-shaped guide,` i with projecting twistedfinger and leteraily- 5 projecting Wings, and the brace-plates for saidwings, forming passages of Contracted width Witnesses: i for the fabric,substantially es specified. WM. D. CONNER,

In testimony whereof we have signed our HARRY SMITH.
